Some, yes and it wasn't uncommon years ago to do just this.
A wall socket (either switched or unswitched) is the place into which the prongs of a plug is plugged in.
If it fits and the controlling ballast or electronics is compatible with the bulb type. The 240 volt socket rating is just and indicator of the maximum voltage that can be applied to the socket.
A three phase motor looks like any other motor from the outside. It might be a little larger than a standard motor but it looks the same. If it is not hardwired but has a plug, the plug will have four prongs instead of three. The socket will look different from a standard socket or the socket for a stove or air conditioner. It will also have four holes. The hole for the ground plug will have a special indent. That makes it so you can not put the plug in wrong. A two phase motor will run the correct way regardless of how you put the plug in the socket. If you would put the plug for three phase motor in the socket the wrong way, the motor would run backwards.
'Voltage' is electromotive force, and the 'Watt' is a unit of power. You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.
It may damage the cord. You may or may not have a problem if you pull a plug from a socket by its cord. The cord contains wires which are attached, inside the plug, to the protruding blades that enter the socket. That attachment may be very firm, or possibly not so firm. In addition, some plugs fit very firmly inside a socket and consequently are difficult to pull out, and others fit very loosely and are easy to pull out. In the worst case scenario, in which the wires are weakly attached inside the plug, and the plug fits firmly in the socket, the result of pulling the plug out by the cord may be that the wires will become disconnected inside the plug, which will then cease to work properly. And even if the wires do not become immediately disconnected, you may be progressively weakening the connection, if you habitually pull out a plug by means of the cord. Eventually the wiring will fail.
If you want to you could remove the light socket and put in an outlet then plug your light into the outlet.
An adapter is needed to use a North American shaver in Europe. European outlets are a different size along with a different voltage that you shaver is rated for. An Adapter will take care of both of these problems.
Just plug it in the socket
No, unless there is an indicator light in the socket.
what is the difference between plug ang socket?
Yes, but you need to check the input voltage on the label of the shaver. Most are 100-240v so it will accept the input ok. The other issue is the type of plug it has on it. Depending whether it is a rechargeable or just plain mains-only shaver it will probably have a two pin plug. If the pins are round, they will fit into any bathroom shaver socket. If they are flat, they are designed to go into a regular wall socket, so you will need a travel plug for the country you are travelling to. <<>> Most shavers are able to use 100-240 v but they have an adjustment which must be set to the new voltage when you change country. My shaver can be switched to 110 v, 120 v , 220 v and 240 v and if it is connected to the wrong voltage it might not work and/or it might be damaged.
Plug and socket, plug and socket outlet, plug and receptacle or plain plug and outlet all seem to be in common usage in the US. Plug and socket is possibly the only wording commonly used in the UK. [Plug and socket outlet sounds ok to a me, as a Brit, but we never really use that expression in the UK. Plug and outlet or plug and receptacle actually sound very strange!]
18 mm spark plug socket
No, the plug and socket are incompatible, and even if you changed the plug, the unit would not operate on such alow voltage.
You need an 18 mm spark plug socket.
5/8" peanut plug socket
If you leave a plug socket on without a plug in it you will lose between 550 to 1,000 health points per 1 swich
